Patents by Inventor Yuuji Imanaga

Yuuji Imanaga has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6920384
    Abstract: A driving force control apparatus for a vehicle includes an accelerator opening sensor that detects an accelerator opening for a vehicle, and an automatic transmission control device that controls an automatic transmission based on road information and the accelerator opening. The automatic transmission control device, in an interval prior to a deceleration required interval, controls an automatic transmission so as to ease a shifting operation that corresponds to a decrease in the accelerator opening.
    Type: Grant
    Filed: December 18, 2002
    Date of Patent: July 19, 2005
    Assignees: Aisin Aw Co. Ltd., Toyota Jidosha Kabushiki Kaisha

  • Patent number: 6725144
    Abstract: A vehicle control apparatus including an automatic transmission which changes a speed of rotation of an input shaft drivingly connected to a driving source and outputs the rotation of the input shaft to an output shaft, and a shift execution device that executes shifting of the automatic transmission, including a shift control device that calculates a predetermined target input shaft rotation number based on road information and vehicle state information, and controls an input shaft rotation number such that the input shaft rotation number becomes equal to the predetermined target input shaft rotation number, by executing shifting of the shift execution device; and a shifting speed setting device that sets a shifting speed, when control based on the road information begins after switching from control based on the vehicle state information by the shift control device, to a predetermined shifting speed such that shifting is executed rapidly, and sets the shifting speed, when shifting needs to be executed durin
